Howdy Trisha!! Thanks so much for your question!
New Fantasyland is amazing!!
I just spoke with a Cast Member, and unfortunately, information is not yet being released regarding the precise opening date of the Princess Fairytale Hall. You are correct that it is scheduled to open in 2013. This elegant royal court will be home to Disney princesses ready to meet their subjects. I can't wait for it to open! I have a little princess myself and she is very exited to see their new "home."
You can visit Belle in Enchanted Tales with Belle. We were there last month and it was wonderful! It is an extremely interactive experience and was enjoyed by both our princess and knight!
You can visit Ariel in her Grotto and you won't want to miss her new attraction, Under the Sea, Journey of the Little Mermaid. You will descend below the "waves" for a splashy musical adventure. We love this new attraction!
You can currently visit other princesses, including Cinderella, Aurora and Rapunzel at Town Square Theater in Magic Kingdom.
Thanks again for your question and please let me know if you have any others as you plan you next magical Disney vacation! Hopefully we will all soon hear something about the Princess Fairytale Hall.
